I have a problem with connecting to Limewire v 1.7

At home, I love limewire and have absolutely no problems connecting and staying connected. At college, however, it is a different story. Usually, it won't connect at all. If it ever does get on a page with some hosts, it will kick me off in less than 20 seconds, therefore never allowing a search or any downloads. I go to a University that has a completely wireless campus, and I know nothing else about the internet here besides that. Any help I could get on fixing this connection problem would be great. thanks
